Title: Ball screw steering apparatus
Inventor: FUTABA TAKESHI
IPC: B62D3/04
Filed: 1979-06-22
Abstract: PURPOSE: To prevent a steering wheel from staggering by a method wherein the axis of the taped hole of a ball nut and the central plane of the central tooth groove of a rack are made to fall at right angles and the tooth side surfaces of the central tooth groove are ground in parallel to the central plane of the tooth groove.  
     CONSTITUTION: The central tooth 1a' of a sector gear 1a interlocks in the central tooth groove 2b' of a rack 2a. The central tooth groove 2b' of the rack 2a is formed smooth by grinding its tooth side surfaces. Further, the ball screw grooves 13 of a ball nut 2 is ground by a grinding shaft which moves at right angles to the central plane of the central tooth groove 2b' of the rack 2a. The force produced in the interlock between the central tooth 1a' of the sector gear 1a and the central tooth groove 2b' of the ball nut 2 can always be operated to the ball nut 2, that is, to the central axis of a ball screw shaft 11. In such a manner, since the rack 2a always interlocks in the central tooth of the sector gear by grinding operation of the ball nut 2 the steering wheel can be prevented from staggering.

Title: Production of hydrogen using ion exchange membrane
Inventor: ODA YOSHIO
IPC: C25B9/19
Filed: 1981-05-25
Abstract: PURPOSE:To produce hydrogen with low voltage by using a porous cathode of carbon powder carrying a platinum metal-based metal and polytetrafluoroethylene for the cathode to be brought into tight contact with a cation exchange  membrane used for an electrolytic method for water. CONSTITUTION:Platinum group metals or their alloys are deposited on carbon  powder of 200-1,300m<2>/g specific surface areas. The gas-and liquid-permeable  cathode constituted of the carbon powder and polytetrafluoroethylene is brought into tight contact with a cation exchange membrane and is used in producing  hydrogen by electrolyzing water. Here, if the specific surface areas of the carbon powder are below the lower limit, it is not possible to deposite said metals sufficiently, and the low overvoltage effect possessed by said metals is not sufficiently provided. Conversely, if in excess of the upper limit, the construction  of the carbon powder per se is embrittled.

IPC: H04M3/00
Filed: 1992-02-28
Abstract: PURPOSE:To attain an unattended maintenance station by transferring automonous message data and remote command data by the No.7 signal system. CONSTITUTION:A remote control function as a user section of a signal connection control section (SCCP) is provided to a common line signal interruption exchange of stations 1, 2 and a remote control command is set in addition corresponding thereto. An automonous message outputted by the maintenance station 2 is outputted to a monitor test seat 4 of the station 2 and a line 5 tying the exchange is used by using the SCCP and transferred to the station 1, and then outputted to a monitor test seat. The remote command applied by the station 1 is transferred similarly by using the SCCP to the station 2 and the reply message being the result of execution is outputted to the test seat 3 of the station 1 by using the SCCP. Thus, the remote maintenance is implemented at the central maintenance station without revision of the system configuration of the maintenance station to realize the unattended maintenance station.

Abstract: PURPOSE: To provide an analytical method for a cornea endothelium cell image in ophthalmic diagnosis capable of simply analyzing the cornea endothelium cell image in a short time to obtain the cell density as data necessary for a doctor's judgement. CONSTITUTION: Signals of a cornea endothelium cell image from a TV camera which has picked up a cornea 1c of a tested eye 1 are taken in a frame memory 3, the cell image is reproduced on a monitor TV 7, and the cell membrane in the longitudinal direction is extracted and converted into fine lines in the frame memory via an arithmetic unit 4 by operating a switch in the upside of an operation panel 6.

Filed: 1981-05-23
Abstract: PURPOSE: To check unnecessary charging and power consumption and keep the interval of photographing constant by carrying out photometry before the time required for the completion of charging to an electronic flashing device and starting the charging when the photometric level falls prescribed number or less.  
     CONSTITUTION: Clocks from an oscillation circuit 2 are counted by a ring counter 3 and, when a high-level signal is inputted to the counter after outputting the prescribed number of counting to a contact 11b of a rotary switch 11, a flip-flop 14 is set up, a photometric signal is outputted and a photometric circuit 18 starts to operate. If the photometric output is smaller than the prescribed number, an electronic flashing device 26 starts charging by an output from a comparator 23. When a high-level signal is outputted to a contact 11a after counting prescribed number, a camera controlling circuit 24 is actuated, the flashing device 26 emits light and the circuit 14 and the counter 3 are reset. When the photometric output is prescribed number of more, the flashing device does not perform charging, but is released.

Title: Laser beam printer
Inventor: KATO JUNICHI
IPC: B41J2/44
Filed: 1987-03-31
Abstract: PURPOSE:To obviate generation of an electrical noise by providing a means for prohibiting the transfer of a developer between a photosensitive body and developer carrier. CONSTITUTION:A solenoid 15 is energized by a control circuit and a shutter 13 is pulled down when the output control of a semiconductor laser light source is started by a driving circuit and an image signal is no more impressed to the laser light source. As a result, a window 13a of the shutter 13 is lowered and the outside peripheral face of a developing sleeve 12 and the outside peripheral face of a photosensitive drum 7 are shut off by the shutter 13. The developer on the sleeve 12 is, therefore, no longer capable of shifting onto the drum 7 and consequently, the latent image on the drum 7 is no longer developed. The transfer of the developer from the developer carrier to the photosensitive body is thereby prohibited without having a need for turning off a power supply for developing bias during the output control period of the laser light source.

Title: Automatic frequency control circuit
Inventor: KOUNO KOUUN
IPC: H03J7/02
Filed: 1988-03-31
Abstract: PURPOSE:To obtain a stable low frequency conversion color sub-carrier by removing a ripple component from the control voltage of a voltage control oscillating circuit(VCO). CONSTITUTION:When the phase of a pulse signal (h) is ahead of the phase of another pulse signal (f), only a pulse signal (j) is outputted, and to the contrary, when the phase of the pulse signal (h) is behind the phase of the pulse signal (f), only a pulse signal (k) is outputted. Further, when the phases of the pulse signals (f) and (h) are coincident, neither the pulse signal (j) nor the pulse signal (k) is outputted. Consequently, the ripple component is never included in control voltage Vc of a VCO 19, and the occurrence of hue dislocation can be prevented under the locked state of automatic frequency control(AFC). Thus, the stable low frequency conversion color sub-carrier can be obtained.

Title: Input processing method
Inventor: IMADA TATSUHIRO
IPC: G05B21/02
Filed: 1982-05-08
Abstract: PURPOSE:To obtain stable and high-precision data, by correcting data, which are obtained by processing n-number of past inputs to the input processing in the method of moving averages, by data obtained by subjecting m-number (m<n) of past inputs to the input processing in the method of moving averages. CONSTITUTION:A true value PVN of a fluctuating water level is given by an equation PVN=PVn+alpha(PVm-PVn). In this equation, PVn is data obtained by subjecting n-number of past water level inputs to the input processing in the method of moving averages, and PVm is data obtained by subjecting m-number of past water level inputs to the input processing in the method of moving averages. As shown by this equation, data PVn is corrected with data PVm. Stable and high-precision data is obtained by this input processing. This method is applied to not only the water level but also an object whose true input value is difficult to obtain because of fluctuation of the input signal.
